To all whom it may concern:

Be it known that I, OLIVIER GoBBn, a subject of the King of Belgium, and resident of Jumet, Belgium, have invented certain new and useful Improvements in or Relating-to Heat-Regenerators for Heating Air or Gases, of which the following is a specification.

In order that a heat regenerator may be air tight, it is necessary that its tightness should not be dependent on the vertical joints of the hollow brickwork of which it consists. As a matter of fact when the temperature of a regenerator increases, the material of the furnace expands and the vertical walls which hold together the mass of the regenerator are slightly pushed outward.

When suflicient cooling occurs, the refractory materials of the furnace shrink andas nothin constrains the vertical walls to follow this shrinkage they remain in their position and small vertical cracks are formed in the regenerator into whichcracks particles torn from the brickwork can penetrate. Every time a variation of temperature .oc-

curs in-the enerator, the same thin is re-- peated and resh particles fall into t e vertical cracks which keep constantly becoming wider. If therefore the air-tightness of a regenerator depends on the vertical joint, or jolnts, the generator becomes of little or no use in a very short time. Now this is just what occurs in most regenerators hitherto constructed and inorder to overcome this serious defect in regenerators of'the present day, I have designed the regenerator which forms the object of the present in-' vention.

The apparatus is shown in transverse section in FigureI, in longitudinal section in Fi II, in horizontal section in Fig. III an in cross section and elevation in Fig. IV- Fi V is a longitudinal section on line 55; Flg. VI; Fi VI is an end elevation of one'of the hol ow blocks out of which the regeneratoris constructed; Fi VII is a side elevation ofa joint cover p ate; and Fig. VIII is a cross, section on line 88, Fi 7.

Fig. I* shows on the right hand side a section at the line KL, Fig. II, while at the left Fig. I shows a section taken at M, N, Fig. II. The left of-Fig. II shows the section taken at-G-I-I, Fig. I,-while the right of Fig. II shows the section taken at EF, Fig. I. The left of Fig. IV shows the section taken at I-J, Fig. II, while the i right side of vation.

Qrdinary hollow bricks b (Fig. V) having neither, tenon, mortise, groove, nor other Fig. IV shows an. end elespecial constructive feature will suflice to construct a regenerator, according to the present invention- Instead of being laid flat on one another with their horizontal faces downward as heretofore, the hollow bricks rest on two inclined faces, the angles of these bricks being atthe top, bottom and on the sides and being spaced apart by plates 79 which cover the butt joints between the ends of adjacent hollow bricks. This special way of laying the bricks has for its object to do away with all the vertical joints of the full faces of these bricks and there are only left the vertical joints of the end faces of these bricks, which joints are without influence on the air tightness of the furnaces, because these vertical joints are closed by butt joint covers held in place by the weight of the bricks. The hollow bricks of this regenerator are slightly spread out internally on one end, as shown in Fig. V.

In the drawings the arrows show how thehot smoke and gases, coming from any furnace through a collecting channel a run in a downward direction around and over the hollow brickwork b with which the smoke and gases come into contact over all its faces, before they pass in a cooled state to the collecting passage 0 which leads them the lowermost row of hollow bricks b and then flows through the regenerator from right to left and returns through the second row in the reverse direction as indicated by the horizontal arrows. Elongated plates fare suitably arranged at the endsof the horizontal passages according to the volume occupied by the air, which volume rapidly increases with the temperature.

The two last rows of heated air unite in a collector g which directs the air to the place where it is to be utilized. The heating of the air is therefore quite methodical, progressive and rational, which result is effected by means of an apparatus which is simple in construction and cheap, occupies little space and can be examined through plugs h provided at'the ends of the horizontal passages.

I claim as my invention 1. A heat regenerator having air flues consisting of horizontal rows of hollow bricks, set up to rest on inclined faces, as described, cover lates for the butt joints at the ends ofadjacent bricks, said cover plates spacing the rows of bricks apart and forming, between superposed and longitudinally adjacent cover plates, a series of passageways'for the flow of heated gases around the hollow bricks and transversely to the flow of air therethrough, substantially as described.

2. A heat regenerator having air flues in superposed layers consisting of horizontal rows of hollow bricks, set up to rest on inclined faces, as described, cover plates for the butt joints at the ends of adjacent bricks, said cover plates spacing the rows of bricks apart and forming, between superposed and longitudinally adjacent cover plates, a series of passageways for the flow of heated gases around the hollow bricks and transversely to the flow of air therethrough, together with means for leading a blast of air in opposite directions through superposed flues, substantially as described.

superposed layers consisting of horizontal rows of hollow bricks, set up to rest' on incllned faces, asdescribed, cover plates for of two subscribing 3. A heat regenerator having air flues in 7 the butt joints at the ends of adjacent bricks, said cover plates spacing the rows of bricks apart and forming, between superposed and longitudinally adjacent cover plates, a series of passageways for the flow of heated gases around the hollow bricks and transversely to the flow of air therethrough, together with adjustable means for leading a blast of air in opposite directions through superposed flues, substantially as described.

4. -A heat regenerator having air flues consisting of horizontal rows of hollow bricks set up to rest on inclined faces, as described, cover plates for the butt joints at the ends of adjacent bricks, said cover plates spacing the rows of bricks apart and forming, between superposed and longitudinally adjacent cover plates a series of passageways, means for leading hot gases downward through said passage-ways around the hollow bricks transversely to the flow of air therethrough, and means for leading an air blast to the lowermost of said air flues and in an opposite direction through superposed flues, substantially as described. l
